Application'filed May l, 1916. Serial No. 95,464.

To all whom at may concern Be it known that I, PERRY S. BAUER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Non-Raveling Bandages, of

which the following is a specification.

This invention relates to surgical bandages and a method of making same and has for its principal. object the provision of relatively inexpensive non-raveling bandages and a method whereby such bandaggs may be manufactured with the greatest facility in any desired width.

Further objects and advantages "of my invention will be apparent as it is better understood by reference to the following specification when read in connection with the accompanying drawing, illustrating the preferred embodiment thereof, in which Figure 1. is a diagrammatic view illustrating the method of manufacturing band ages according to my invention; 2 is view in perspective of a section of fabric treated according to my method, and Fig. 3 is'a view in erspective of a portion of the finished ban age.

ll am aware that non-traveling bandages have been manufactured heretofore in which pairs of warp threads coarser than those employed in the body of the fabric are woven into the fabric at intervals. Bandages are not, however, customarily manufactured by weavers of the fabric and inasmuch as the demand for bandages of any particular width varies cannot be an ticipated it has previously been impossible to supply at short notice quantities of non l v ling bandages of this character conrorming to defin te specifications of width unless a supz -iy of the fabric having the pairs of coarser warp threads properly spaced is at hand. it will be apparent, therefore, that a method which makes it pos sible for the manufacturer to readily supply nonraveling bandages conforming to definite specifications of width without reourse to the weaver and the Product resulting from this method till a long-felt need in the My method of manufacturing non-raveling bandages comprises stitching the fabric in pairs of contiguous parallel lines, the pairs of contiguous lines of stitching being spaced apart a distance substantially equal to the width of the bandages, and sub sequently cutting the fabric between the contiguous lines of stitching. Bandage fabric is supplied in rolls, as indicated at 5 in Fig. l of the drawing, and may be separated into bandages of the desired width by suitable machines such as those disclosed in the patents to Otto C. Schulz No. 1,026,283 and No. 1,109,18 granted roll of fabric; After the stitching has been accomplished the fabric may pass directly to the cutting disks illustrated in the above-mentioned patents or the material may be re-rolled and subsequently out manually or on suitable machines. I

To better illustrate the method the fabric 6 is illustrated in Fi l as separated at 8 between the lines o stitching 7 forming separate bandage strips 9. i

Fig. 2 illustrates on a somewhat larger scale the fabric 6 provided with the contiguous lines 7 of stitching ready for the cutting operation, the separation of the fabric 6 into bandage strips 9 being also indicated.

Fig. 3 illustrates the appearance of a section of a finished bandage '9 provided at either edge with stitching 7 which efiectually prevents the warp threads from raveling. ldaveling has been a common defect of many forms of fabric bandages despite the attempts of manufacturers to remove the loose warp threads at the edges of the bandages and is a serious disadvantage inasmuch as detached threads are likely'to become embedded in a wound which must sometimes be opened after it has partially healed to remove this foreign material.

It will be readily understood from the foregoing that I have perfected a non-raveling bandage which has numerous advantages over bandages as known in the prior art and that my method of making such bandages is superior to methods heretofore employed inasmuch as I am enabled to pre 'D pare bandages of any desired Width as rap idly as the fabric can be cut.

It will be apparent that various changes may be made in the form construction and arrangement of the parts Without departing from the spirit and scope of the invention or sacrificing any of its material advantages, the form hereinbefore described being merely preferred embodiment thereof.

I claim:

1. A method of making fabric bandages which comprises stitching the complete fabric in pairs of contiguous parallel lines, the distance between the pairs of contiguous lines of stitching being substantially equal to the desired Width of the bandage, and subsequently cutting the fabric between the contiguous lines of stitchin 2. A method of making fabric bandages which comprises stitching the, complete 'fabric in pairs of contiguous parallel lines,

bandage having a thread stitched to the,

fabric in spaced relation With its lateral edges, whereby raveling is prevented.

4. As an article of manufacture, a surgical bandage cloth having a plurality of pairs of contiguously disposed threads stitched to the complete fabric, the distance between the pairs of contiguously disposed threads being 3 substantially equal to the desired Width of individual bandages.
